Electrochemical and photoelectrochemical oxidation processes for polystyrene microplastic treatment: BDD anode vs Sb-doped SnO2 ceramic anode coated with a CdFe2O4 photocatalytic layer
Summary
Researchers tested two electrode types — a boron-doped diamond anode and a tin-oxide ceramic anode coated with a cadmium ferrite photocatalyst — for breaking down polystyrene microplastics using electrical current, with and without visible light. The study tracked removal efficiency, carbon mineralization, and energy consumption to compare the two systems. Findings help identify more sustainable and effective electrochemical methods for treating microplastic-contaminated water.
This dataset contains experimental data obtained during the electrochemical and photoelectrochemical degradation of polystyrene (PS) microplastics in aqueous media. Experiments were performed at room temperature using two anode materials: a commercial boron‑doped diamond (BDD) anode and a Sb‑doped SnO₂ ceramic anode coated with a photoactive cadmium ferrite (CdFe₂O₄) layer. The dataset includes the temporal evolution of PS removal efficiency, total organic carbon (TOC) mineralization, kinetic model fitting parameters, raman spectroscopic analysis and specific energy consumption under different applied current intensities (50, 100, and 200 mA) and illumination conditions (dark and visible light).
